Originally a naval base, Comagena, and later a center for the Babenberg dynasty, Tulln is one of the most ancient towns in Austria. Located on the right bank of the Danube, it is called "the flower town" because of the masses of blossoms tourists can see in spring and summer. It's the place, according to the saga of the Nibelungen, where Kriemhild, the Burgundian princess of Worms, met Etzel, king of the Huns.
